- I-A&Q ye-PCB, Kungani i-solder mask plug hole?
1. Kungani i-BGA itholakala emgodini we-solder mask?Liyini izinga lokwamukela?Re: Okokuqala, imbobo yepulaki yemaski ye-solder iwukuvikela impilo yesevisi ye-via, ngoba imbobo edingekayo endaweni ye-BGA ngokuvamile incane, phakathi kuka-0.2 no-0.35mm.Enye isiraphu akulula ukuba yomiswe noma ihwamuke, futhi kulula ukushiya izinsalela.Uma imaski ye-solder ingaxhumi imbobo noma ipulaki...
- I-A&Q ye-PCB (2)
9. Kuyini isinqumo?Impendulo: Phakathi nebanga elingu-1mm, ukulungiswa kwemigqa noma imigqa yesikhala engakhiwa ukuphikiswa kwefilimu eyomile nakho kungavezwa ngosayizi ophelele wemigqa noma izikhala.Umehluko phakathi kwefilimu eyomile nokuqina kwefilimu yokumelana Ukuqina kwefilimu ye-polyester kuhlobene.Ukuqina kwesendlalelo sefilimu yokumelana, kuyancipha ukulungiswa.Lapho ukukhanya...
- Impahla Ehlukile Yebhodi Lesekethe
Ukusha kwento ethile, eyaziwa nangokuthi i-flame retardancy, ukuzicisha, ukumelana nelangabi, ukumelana nelangabi, ukumelana nomlilo, ukuvutha nokunye ukuvutha, ukuhlola ikhono lempahla ukumelana nokusha.Isampula lento evuthayo ibaswa ngelangabi elihlangabezana nezimfuneko, futhi ilangabi liyasuswa ngemva kwesikhathi esishiwo.Izinga lokuvutha li...
- Ibhodi le-Ceramic PCB
Amabhodi wesifunda se-Ceramic empeleni enziwe ngezinto zobumba ze-elekthronikhi futhi angenziwa abe yizimo ezihlukahlukene.Phakathi kwabo, ibhodi lesifunda se-ceramic linezici ezivelele kakhulu zokumelana nokushisa okuphezulu kanye nokufakwa kukagesi okuphezulu.Inezinzuzo zokungaguquguquki kwe-dielectric ephansi, ukulahleka kwe-dielectric ephansi, ukuhanjiswa okuphezulu kwe-thermal, ukuzinza okuhle kwamakhemikhali, nokunwetshwa okufanayo kokushisa ...
- Indlela yokwenza i-pcb kuphaneli?
1. Uhlaka lwangaphandle (uhlangothi olubambayo) lwephaneli Yebhodi Lesifunda Eliphrintiwe kufanele lusebenzise idizayini evala iluphu ukuze kuqinisekiswe ukuthi ijigsaw ye-PCB ngeke ikhubazekile ngemva kokulungiswa endaweni;2. Ububanzi bephaneli ye-PCB ≤260mm (umugqa we-SIEMENS) noma ≤300mm (umugqa we-FUJI);uma ukukhishwa okuzenzakalelayo kuyadingeka, ububanzi bephaneli ye-PCB× ubude ≤125 mm×180 mm;3. Umumo we-PCB jigsaw kufanele usondele eduze kwesikwele ngokungenzeka...
- Indlela yokuvimbela i-PCB board warping ngesikhathi senqubo yokukhiqiza
I-SMT(Printed Circuit Board Assembly, PCBA) ibizwa nangokuthi ubuchwepheshe be-surface mount.Phakathi nenqubo yokukhiqiza, i-solder paste iyashiswa futhi incibilike endaweni yokushisa, ukuze amaphedi e-PCB ahlanganiswe ngokuthembekile nezingxenye ze-surface mount ngokusebenzisa i-solder paste alloy.Le nqubo siyibiza ngokuthi i-reflow soldering.Iningi lamabhodi esekethe lithambekele ekugobeni nasekwenzeni ibhodi uma lihlehliswa...
- I-HDI board-high density interconnect
Ibhodi le-HDI, ukuminyana okuphezulu kokuxhumana okuphrintiwe ibhodi lesifunda Amabhodi e-HDI angobunye bobuchwepheshe obukhula ngokushesha kuma-PCB futhi manje butholakala e-ABIS Circuits Ltd. Amabhodi e-HDI aqukethe ama-vias angaboni kanye/noma angcwatshwe, futhi ngokuvamile aqukethe ama-microvias angu-0.006 noma amancane ububanzi.Banobuningi besifunda obuphakeme kunamabhodi wesifunda wendabuko.Kunezinhlobo eziyisi-6 ezihlukene zamabhodi we-HDI PCB, ukusuka phezulu kuye ku-su...
- Ibhodi Lesifunda Eliphrintiwe |Ukwethulwa kweSilkscreen
Iyini i-Silkscreen ku-PCB?Uma uklama noma u-oda amabhodi esekethe akho aphrintiwe, ingabe udinga ukukhokha okwengeziwe ngesikrini sikasilika?Kukhona imibuzo odinga ukuyazi ukuthi yini isikrini sikasilika?Futhi isikrini sikasilika sibaluleke kangakanani ekwenziweni kwebhodi lakho le-PCB noma i-Printed Circuit Board Assembly?Manje i-ABIS izokuchazela.Yini isikrini sikasilika?Isikrini sikasilika ungqimba lwemikhondo kayinki esetshenziselwa ukuhlonza izingxenye, ...
